!!! warning ""
If tun is running in non-privileged mode, addresses and MTU will not be configured automatically, please make sure the settings are accurate.
### Fields
#### interface_name
Virtual device name, automatically selected if empty.
#### address
!!! question "Since sing-box 1.10.0"
IPv4 and IPv6 prefix for the tun interface.
#### inet4_address
!!! failure "Deprecated in sing-box 1.10.0"
`inet4_address` is merged to `address` and will be removed in sing-box 1.11.0.
IPv4 prefix for the tun interface.
#### inet6_address
!!! failure "Deprecated in sing-box 1.10.0"
`inet6_address` is merged to `address` and will be removed in sing-box 1.11.0.
IPv6 prefix for the tun interface.
#### mtu
The maximum transmission unit.
#### gso
!!! question "Since sing-box 1.8.0"
!!! quote ""
Only supported on Linux with `auto_route` enabled.
Enable generic segmentation offload.
#### auto_route
Set the default route to the Tun.
!!! quote ""
To avoid traffic loopback, set `route.auto_detect_interface` or `route.default_interface` or `outbound.bind_interface`
!!! note "Use with Android VPN"
By default, VPN takes precedence over tun. To make tun go through VPN, enable `route.override_android_vpn`.
#### iproute2_table_index
!!! question "Since sing-box 1.10.0"
Linux iproute2 table index generated by `auto_route`.
`2022` is used by default.
#### iproute2_rule_index
!!! question "Since sing-box 1.10.0"
Linux iproute2 rule start index generated by `auto_route`.
`9000` is used by default.
#### auto_redirect
!!! question "Since sing-box 1.10.0"
!!! quote ""
Only supported on Linux with `auto_route` enabled.
Automatically configure iptables/nftables to redirect connections.
*In Android*
Only local IPv4 connections are forwarded. To share your VPN connection over hotspot or repeater,
use [VPNHotspot](https://github.com/Mygod/VPNHotspot).
*In Linux*:
`auto_route` with `auto_redirect` works as expected on routers **without intervention**.
#### auto_redirect_input_mark
!!! question "Since sing-box 1.10.0"
Connection input mark used by `route_address_set` and `route_exclude_address_set`.
`0x2023` is used by default.
#### auto_redirect_output_mark
!!! question "Since sing-box 1.10.0"
Connection output mark used by `route_address_set` and `route_exclude_address_set`.
`0x2024` is used by default.
#### strict_route
Enforce strict routing rules when `auto_route` is enabled:
*In Linux*:
* Let unsupported network unreachable
* Make ICMP traffic route to tun instead of upstream interfaces
* Route all connections to tun
It prevents IP address leaks and makes DNS hijacking work on Android.
*In Windows*:
* Add firewall rules to prevent DNS leak caused by
Windows' [ordinary multihomed DNS resolution behavior](https://learn.microsoft.com/en-us/previous-versions/windows/it-pro/windows-server-2008-R2-and-2008/dd197552%28v%3Dws.10%29)
It may prevent some applications (such as VirtualBox) from working properly in certain situations.
#### route_address
!!! question "Since sing-box 1.10.0"
Use custom routes instead of default when `auto_route` is enabled.
#### inet4_route_address
!!! failure "Deprecated in sing-box 1.10.0"
`inet4_route_address` is deprecated and will be removed in sing-box 1.11.0, please use [route_address](#route_address)
instead.
Use custom routes instead of default when `auto_route` is enabled.
#### inet6_route_address
!!! failure "Deprecated in sing-box 1.10.0"
`inet6_route_address` is deprecated and will be removed in sing-box 1.11.0, please use [route_address](#route_address)
instead.
Use custom routes instead of default when `auto_route` is enabled.
#### route_exclude_address
!!! question "Since sing-box 1.10.0"
Exclude custom routes when `auto_route` is enabled.
#### inet4_route_exclude_address
!!! failure "Deprecated in sing-box 1.10.0"
`inet4_route_exclude_address` is deprecated and will be removed in sing-box 1.11.0, please
use [route_exclude_address](#route_exclude_address) instead.
Exclude custom routes when `auto_route` is enabled.
#### inet6_route_exclude_address
!!! failure "Deprecated in sing-box 1.10.0"
`inet6_route_exclude_address` is deprecated and will be removed in sing-box 1.11.0, please
use [route_exclude_address](#route_exclude_address) instead.
Exclude custom routes when `auto_route` is enabled.
#### route_address_set
!!! question "Since sing-box 1.10.0"
!!! quote ""
Only supported on Linux with nftables and requires `auto_route` and `auto_redirect` enabled.
Add the destination IP CIDR rules in the specified rule-sets to the firewall.
Unmatched traffic will bypass the sing-box routes.
Conflict with `route.default_mark` and `[dialOptions].routing_mark`.
#### route_exclude_address_set
!!! question "Since sing-box 1.10.0"
!!! quote ""
Only supported on Linux with nftables and requires `auto_route` and `auto_redirect` enabled.
Add the destination IP CIDR rules in the specified rule-sets to the firewall.
Matched traffic will bypass the sing-box routes.
Conflict with `route.default_mark` and `[dialOptions].routing_mark`.
#### endpoint_independent_nat
!!! info ""
This item is only available on the gvisor stack, other stacks are endpoint-independent NAT by default.
Enable endpoint-independent NAT.
Performance may degrade slightly, so it is not recommended to enable on when it is not needed.
#### udp_timeout
UDP NAT expiration time.
`5m` will be used by default.
#### stack
!!! quote "Changes in sing-box 1.8.0"
:material-delete-alert: The legacy LWIP stack has been deprecated and removed.
TCP/IP stack.
| Stack | Description |
|----------|-------------------------------------------------------------------------------------------------------|
| `system` | Perform L3 to L4 translation using the system network stack |
| `gvisor` | Perform L3 to L4 translation using [gVisor](https://github.com/google/gvisor)'s virtual network stack |
| `mixed` | Mixed `system` TCP stack and `gvisor` UDP stack |
Defaults to the `mixed` stack if the gVisor build tag is enabled, otherwise defaults to the `system` stack.
#### include_interface
!!! quote ""
Interface rules are only supported on Linux and require auto_route.
Limit interfaces in route. Not limited by default.
Conflict with `exclude_interface`.
#### exclude_interface
!!! warning ""
When `strict_route` enabled, return traffic to excluded interfaces will not be automatically excluded, so add them as well (example: `br-lan` and `pppoe-wan`).
Exclude interfaces in route.
Conflict with `include_interface`.
#### include_uid
